3x Adapters (Danfoss RA, Danfoss RAV, Danfoss RAVL)
Intended use
With Comet Z-wave, you have acquired a programmable radiator thermo-
stat, which can be used to regulate temperature in closed rooms and thus
can contribute to a reduction in heat energy. Please use the regulator for
this purpose only.
Safety instructions
Never recharge, short-circuit or disassemble the batteries - danger
of explosion! Remove expired batteries from the device immediately.
Shield batteries from strong heat - increased risk of leakage!
Do not use new and old batteries together. Clean batteries and device
contact before installation if necessary. Keep batteries away from
children. Avoid contact with skin, eyes and mucous membranes.
Rinse areas affected by battery acid with clean water immediately
and seek medical advice.
Description
Comet Z-wave is a Z-Wave radio standard compatible
energy-saving radiator thermostat.
Use
The installation of the Comet Z-waves can easily be installed on all known
valve bottom sections; without dirt or water spots because the heating
circuit is not interrupted.
1. Fully unscrew the old thermostat, loosen the fi tting
and remove from the valve.
2. 2. Remove the battery cover, by pressing it upwards on the marked spot
(1) and take it off its hinges (2).
(1)
(2)
Install the batteries as shown. Do not use rechargeable batteries!
Ensure correct polarity! PREP appears on the display. The motor will
start completely in order to facilitate installation. As soon as the regulator
is installation-ready, INST appears on the display. The fl ashing radio
symbol signals that the device is ready to be enrolled. Start the enrolment
procedure (Inclusion) on your Gateway/Controller in order to include the
device in the network.
3. Screw the union nut (ring on product) on the valve. If the union nut does
not fi t on you valve, you probably need an adapter.
4. Press the button in the battery compartment. The energy-saving thermo
stat shows ADAP in the display and carries out an initialisation run.
After initialisation, the energy-saving thermostat shows the main screen.
INFO When an error occurs, an error code is shown.
Look in the „Help“ table.
No adapter is required for the following valves:
Heimeier, Junkers Landys+Gyr, MNG, Honeywell Braukmann, since
these have thread dimensions of M30 x 1.5 mm. Adapters for Danfoss
RAV (pin must be put on the valve tappet) Danfoss RA and Danfoss
RAVL are enclosed.
An adapter is required for the following valves:
Herz M28 x 1.5 mm, Comap M28 x 1.5 mm, Vaillant 30.5 mm, Oventrop
M30 x 1.0 mm, Meges M38 x 1.5 mm, Ondal M38 x 1.5 mm, Giacomini
22.6 mm, Rossweiner M33 x 2.0 mm, Markaryd M28 x 1.0 mm, Ista M32
x 1.0 mm, Vama M28 x 1.0 mm, Pettinaroli M28 x 1.5 mm, T+A M28 x 1.5
mm or Gampper 1,2,6. These can be found at www.eurotronic.org
Please fully remove the plastic connectors before you use one of the
enclosed adapters! Please fully remove the connecting rods marked
in grey before installing the adapter!
Addition/removal to/from the network
In order to enrol and delete the device manually, start the enrolment /
deletion process of your central unit/gateway. Press and hold the
button in the battery compartment of the Comet Z-wave for 5
seconds. The device moves into installation position in order
to enable (de)installation.
Operation and display elements on the display
1. Bat tery empty
2. Comfort temperature active
3. Economy temperature active
4. Window-/frost protection function active
5. Wireless active
6. AUTO or MANU mode active
7. Adjusting wheel + and -
8. Button in bat tery compartment
Basic modes of operation
AUTO mode
The Comet Z-wave regulates temperature as per factory settings or
wireless set-up
Factory settings
Comfort temperature (Factory settings 22°C)
Economy temperature (Factory settings 18°C)
MANU mode
Comet Z-wave switches to MANU mode when you change the
temperature by hand on the adjusting wheel. The setting overwrites
the wireless set-up for two hours. After this, the setting changes
automatically to the previously-programmed setting. If you wish to
change the settings prior to this, you may do this via wireless.
Standby
The screen switches off 30 seconds after the last entry on the device
to save electricity. The display can be switched on again by turning the
adjusting wheel in any direction.
Frost protection, open window recognition and hard water protection
functions are automatically active.
Frost protection function
If the temperature falls below 6°C, the energy-saving thermostat
opens the valve until the temperature rises above 8°C again.
This stops the radiator from freezing.
Hard water function
To avoid calcifi cation of the radiator valves, the energy-saving
thermostat carries out a hard water protection cycle once a week.
Open window function
If the temperature falls sharply, open window recognition is activated
and the open window active symbol is shown. In this instance, the
valve is closed for 15 minutes.
Uninstallation
In order to uninstall the energy-saving thermostat, press and hold the
button down for 3 seconds. The device moves into the installation po-
sition. When the installation position has been reached (display shows
INST), youmay take out the bat teries and unscrew the energy-saving
thermostat from the valve.
Cleaning
Use only a dry to lightly-damp cloth to clean the Comet Z-wave.
Avoid using chemical solvents,. They may damage the device.

Problem Cause Solution
Batteries do not have
enough power.
Replace batteries.
Heating
element
does not
warm up.
Is the boiler water
temperature O.K.?
Valve does not open,
is it calcifi ed after
the summer pause/
heating pause?
Adjust the temperature of
the boiler water.
Remove the Comet
Z-wave, move the valve
back and forth per hand or
with a tool.
Heating
element

Valve does not close
completely. It may be
that the closing point
of your valve seat has
shifted.
Adapt again (see
“Adapting”) Move the
valve stem several times
by hand, it may be that
adaptation is impossible
because your valve is
calcifi ed or the seat
no longer performs its
function.
Pressure
piece falls
out (This
can also
cause an
E1-error)
Due to an endless
thread the pressure
piece, which is situ-
ated at the bottom,
can fall out if the
device has not been
af fi xed on the
valve.
Put in the pressure
piece. Press the Button
for 3 sec.
The endless thread is
rotating now and fi xes
the pressure piece
again. Just install it to
the radiator and adapt
it once again.
E1-E3 Press the button for 3 seconds. The fault indication
is deleted. The device moves to the mounting posi-
tion (display shows PREP or INST).
E1 No adaptation

installed to the heater.
Is the installation OK?
Install Comet Z-Wave
to the heater.
E2 Valve stroke is too
short.
